For just a few current examples, try Cardinal Mahoney, Katharine Jefferts Schori, anyone associated with the World Council of Churches, the Presbyterian Church USA, Jesse Jackson, Al Sharpton, and on and on and on.
You can even add Bush in there - he believes that tax money should be used for things better left to private charity.
Just google "social justice" and see what I mean.
Are these people real Christians or are they politicos disguising themselves as Christians to get the tax free designation as a church?
Anytime I see the phrase "social justice" I read "Communism".
This is all dependent on whose definition of "Christian" you want to use, and whose definition of "socialism" as well.
